To examine species composition, abundance and biomass of fishes in the northwestern East Sea of Russian EEZ, trawl survey were conducted at 31 sampling stations from 2006 to 2008. Also, trawl survey were conducted at 21 sampling stations in the southwestern East Sea of Korean EEZ from 2006 to 2008. A total of 67 fishes were collected in the northwestern East Sea of Russian EEZ, a total of 39 fishes were collected in the southwestern East Sea of Korean EEZ. Among them, a total of 53 fishes were collected in the northwestern East Sea of Russian EEZ only, and a total of 25 fishes were collected in the southwestern East Sea of Korean EEZ only. Mean abundance per area which caught by trawl survey in the northwestern East Sea ranged from a high of $116,478inds./km^2$ in 2008 to a low of $19,737inds./km^2$ in 2006. And mean abundance per area in the southwestern East Sea ranged from a high of $89,129inds./km^2$ in 2006 to a low of $8,234inds./km^2$ in 2008. Mean biomass per area which caught by trawl survey in the northwestern East Sea ranged from a high of $11,333kg/km^2$ in 2008 to a low of $2,439kg/km^2$ in 2006. And mean biomass per area in the southwestern East Sea ranged from a high of $6,273kg/km^2$ in 2006 to a low of $1,062 kg/km^2$ in 2008. Cluster analysis, based on a Bray-Curtis similarity matrix of fourth root transformed data of number of species and individuals per area, showed division into three different groups by depth in the northwestern and southwestern East Sea.

Objectives The purpose of this study is to provide data for development of the korean medicine (KM) clinical practice guidelines (CPG) for growth disorder (GD) by identifying the awareness and knowledge needs of KM doctors (KMD) through online survey. Methods Survey questionnaire was produced by referring to the previous recognition survey studies for clinical KMDs. The survey questionnaire was composed 18 questions regarding the current status of clinical care for GD, clinician's knowledge level about GD, and other details that clinicians use during practice. The survey was conducted from January 2021 to March 2021. An online survey was conducted on 101 KMDs from the association of pediatrics of KM. Results According to the survey, 96 respondents (40.3%) said the causation of GD without growth hormone deficiency needs to be included in CPG. 96 (23.5%) of the respondents wishes to utilize percentile in diagnosis and evaluation of the growth assessment. 24.7% of the clinicians were using the herbal medicine treatment. Currently, when treating with KM for GD, herbal medicine (100%) is the most widely used, followed by acupuncture (77.6%), and moxibustion (36.7%). In terms of a complex treatment, growth therapy efficacy (26.8%) is shown to be the most important factor to consider and needed to be included in CPG for the complex treatment, and diet (22.3%) is also considered to be important in GD. Conclusions In this study, we were able to understand the clinical KMDs' perception of GD, knowledge level, and the requirements in the CPG. The results of this study will provide the basic data for development of CPG for GD.

Recently, the rapidly growing new generation of renewable energy projects has emerged as an artificial building that creates a mix of natural environments and disruption to the environment. It serves as a quality inhibitor for rural landscapes and implies the absence of favorable rural landscape. Therefore, the study looked at the color scheme of residents, visitors, and experts in the village, which changed the color of the landscape, and analyzed the color scheme of residents, visitors, and experts. In order to do so, the village was divided into three types and conducted a survey by the general public and experts. In the case of the survey, residents of the three districts (Yeoju, Dam yang, Jeju) were surveyed for 210 residents, and the survey conducted a survey and analysis of 30 people in the area. As a result, both the general public and experts recognized the color change in the energy business, which resulted in the identification of associations and colors of the village. In addition, the recognition and satisfaction of the current situation showed that the education programs for the public were more important than the professionals, as the public show ed low levels of public awareness. Based on this research, we expect to be able to utilize the plan as a guideline for the project of installing solar panels, which is expected to be implemented in the beginning of the project, and can be used as a guideline for the establishment of the solar panels.

A giant jellyfish (Nemopilema nomurai), which is presumed developing in the East China Sea, is recently one of major issues in the Northeast Asia region due to its fatal damage to the fishery. The biomass estimates have generally been conducted by trawl sampling and sighting survey methods. The biological research is also needed to clarify such environmental origin or diurnal migration patterns. While trawl sampling or sighting survey methods are effective to investigate its density estimates in its distributed community of near bottom or surface, they have a problem in investigation on the vertical distribution of jellyfishes. In this case, an echo sounding detection would have an advantage to survey it more extensively and effectively. This trial was conducted to observe the vertical distribution of giant jellyfish, where thermocline strongly formed, during mooring at each station of the East China Sea and southern coastal area using acoustical and optical methods. By the results, they were observed to exit and move at the water column under the thermocline using the optical camera and echo sounder system, and the information was analyzed to find out the acoustical sound scattering characteristics relatives to 120kHz frequency. These results can be utilized effectively to estimate the vertical distribution and biomass of Giant jellyfish with comparing results from trawl sampling and sighting survey methods, hereafter.

This study was conducted to provide basic data for optimal fisheries management through the accurate understanding the catches, fishing level, species composition, distribution characteristics and fisheries status of trammel net in Gangwon Province. As the results of trammel net survey, Pisces were collected 77 species, 1,983.0 kg, Crustacea 9 species, 569.0 kg, Cephalopoda 5 species, 75.3 kg, Gastropoda 12 species, 16.5 kg in the coastal waters of Sokcho and Pisces 55 species, 3,681.5 kg, Crustacea 6 species, 2,229.8 kg, Gastropoda 10 species, 72.8 kg, Cephalopoda 4 species, 10.1 kg in the coastal waters of Donghae, respectively. The catches of important species with season and depths showed that the main target species is Pleuronectidae spp. at all depth and Aptocyclus ventricosus at <100 m in Sokcho, Liparis spp. and Dasycottus setiger at 200-500 m in Donghae, respectively. The mean total length (cm) of Gadus macrocephalus and Aptocyclus ventricosus didn't appear significant difference, but the mean total length of Pleuronectidae spp., Liparis spp. and D. setiger in Donghae is bigger than in Sokcho. From the cluster and MDS analysis based on Bray-Curtis similarity matrix of fourth root transformed, catches data of dominant species in the coastal waters of Sokcho and Donghae was divided into three different groups of the demersal organisms community in 12 survey of Donghae (Group A) and Jul., Oct.-Dec. survey of Sokcho (Group B) and Jan.-Jun. and Aug.-Sep. survey of Sokcho (Group C).

The Survey on the Industrial Research and Development(R&D) is the primary source of information on R&D performed by Korea industrial sector. The results of the survey are used to assess trends in R&D expenditures. Government agencies, corporations, and research organizations use the data to investigate productivity determinants, formulate tax policy, and compare individual company performance with industry averages. Recently, Korea Industrial Technology Association(KOITA) has collected the data by complete enumeration. Koita has, currently, considered sample survey because the number of R&D institutions in industry has been dramatically increased. This study develops survey design for the industrial research and development(R&D) statistics by introducing a sample survey. Companies are divided into 8 groups according to the amount of R&D expenditures and firm size or type. We collect the sample from 24 or 8 sampling strata and compare the results with those of complete enumeration survey. The estimates from 24 sampling strata are not significantly different to the results of complete enumeration survey. We propose the survey design as follows: Companies are divided into 11 groups including the companies of which R&D expenditures are unknown. All large companies are included in the survey and medium and small companies are sampled from 70% and 3%. Simple random sampling (SRS) is applied to the small company partition since they show uniform distribution in R&D expenditures. The independent probability proportionate to size (PPS) sampling procedure may be applied to those companies identified as 'not R&D performers'. When respondents do not provide the requested information, estimates for the missing data are made using imputation algorithms. In the future study, new key variables should be developed in survey questionnaires.
